All organizations must prepare for cyber-crime occurring on their computer systems and within their networks. Demand has never been greater for analysts who can investigate crimes such as fraud, insider threats, industrial espionage, employee misuse, and computer intrusions. Government agencies increasingly require trained media exploitation specialists to recover vital intelligence from Windows systems. To help solve these cases, SANS is training a new cadre of the world's best digital forensic professionals, incident responders, and media exploitation experts capable of piecing together what happened on computer systems second by second.

FOR408: Windows Forensic Analysis focuses on building in-depth digital forensics knowledge of Microsoft Windows operating systems. You can't protect what you don't know about, and understanding forensic capabilities and artifacts is a core component of information security. You will learn how to recover, analyze, and authenticate forensic data on Windows systems, track particular user activity on your network, and organize findings for use in incident response, internal investigations, and civil/criminal litigation. You will be able to use your new skills to validate security tools, enhance vulnerability assessments, identify insider threats, track hackers, and improve security policies. Whether you know it or not, Windows is silently recording an unbelievable amount of data about you and your users. FOR408 teaches you how to mine this mountain of data.

Proper analysis requires real data for students to examine. The completely updated FOR408 course trains digital forensic analysts through a series of new hands-on laboratory exercises that incorporate evidence found on the latest Microsoft technologies (Windows 7, Windows 8/8.1, Windows 10, Office and Office365, cloud storage, SharePoint, Exchange, Outlook). Students leave the course armed with the latest tools and techniques and prepared to investigate even the most complicated systems they might encounter. Nothing is left out - attendees learn to analyze everything from legacy Windows 7 systems to just-discovered Windows 10 artifacts.

FOR408 is continually updated. The course uses an intellectual property theft and corporate espionage case that took over six months to create. You work in the real world, so your training should include real-world practice data. Our instructor development team used incidents from their own investigations and experiences to create an incredibly rich and detailed scenario designed to immerse students in an actual investigation. The case demonstrates the latest artifacts and technologies an investigator might encounter while analyzing Windows systems. The detailed workbook shows step-by-step the tools and techniques that each investigator should employ to solve a forensic case.

For multi-course live training events, there will be a set up time from 8:00-9:00am on the first day only to make sure that computers are configured correctly to make the most of class time. All students are strongly encouraged to attend.

Course Syllabus

FOR408.1: WINDOWS DIGITAL FORENSICS AND ADVANCED DATA TRIAGE

Overview

The Windows Forensic Analysis course starts with an examination of digital forensics in today's interconnected environments and discusses challenges associated with mobile devices, tablets, cloud storage, and modern Windows operating systems. We will discuss how modern hard drives, such as Solid State Devices (SSD), can affect the digital forensics acquisition process and how analysts need to adapt to overcome the introduction of these new technologies.

Hard drive sizes are increasingly difficult to handle appropriately in digital cases. Being able to acquire data in an efficient and forensically sound manner is crucial to every investigator today. Most fundamental analysts can easily image a hard drive using a write blocker. In this course, we will review the core techniques while introducing new triage-based acquisition and extraction capabilities that will increase the speed and efficiency of the acquisition process. We will demonstrate how to acquire memory, the NTFS MFT, Windows logs, Registry, and critical files that will take minutes to acquire instead of the hours or days currently spent on acquisition.

We will also begin processing our collected evidence using stream-based and file-carving-based extraction capabilities that employ both commercial and open-source tools and techniques. Seasoned investigators will need to know how to target the specific data they need to begin to answer fundamental questions in their cases.

Exercises

Install the Windows SIFT Workstation and get an orientation about its operations

Image a hard drive for evidence using a Wiebetech Ultradock Write Blocker

Overview

Our journey continues with the Windows Registry, where the digital forensic investigator will learn how to discover critical user and system information pertinent to almost any investigation. Each examiner will learn how to navigate and examine the Registry to obtain user profile data and system data. The course teaches forensic investigators how to prove that a specific user performed keyword searches, ran specific programs, opened and saved files, perused folders, and used removable devices.

Throughout the section, investigators will use their skills in a real hands-on case, exploring the evidence and analyzing evidence.

Exercises

FOR408.3: CORE WINDOWS FORENSICS PART II: USB DEVICES AND SHELL ITEMS

Overview

Being able to show the first and last time a file or folder was opened is a critical analysis skill. Utilizing shortcut (LNK), jump list, and Shellbag databases through the examination of SHELL ITEMS, we can quickly pinpoint which file or folder was opened and when. The knowledge obtained by examining SHELL ITEMS is crucial in tracking user activity in intellectual property theft cases internally or in tracking hackers.

Removable storage device investigations are often an essential part of performing digital forensics. We will show you how to perform in-depth USB device examinations on Windows 7-10. You will learn how to determine when a storage device was first and last plugged in, its vendor/make/model, and even the unique serial number of the device used.

Exercises

Track USB and BYOD devices that were connected to the system via the Registry and file system

Determine first and last connected times of USB devices that are plugged into your system

Determine last removal time of USB devices that are plugged into your system

Use Shortcut (LNK) file analysis to determine first/last times a file was opened

Use Shellbag Registry Key Analysis to determine when a folder was accessed

Use a jump list examination to determine when files were accessed by specific programs

Overview

Depending on the type of investigation and authorization, a wealth of evidence can be unearthed through the analysis of e-mail files. Recovered e-mail can bring excellent corroborating information to an investigation, and its informality often provides very incriminating evidence. It is common for users to have an e-mail that exists locally on their workstation, on their company e-mail server, in the private cloud, and in multiple webmail accounts.

Additional artifacts such as Windows prefetch and appcompatcache data are paramount to proving evidence of execution. Also, the System Resource Usage Monitor (SRUM), one of the newest digital artifacts, can help determine several important user actions even after execution of counter-forensic programs.

Finally, Windows event log analysis has solved more cases than possibly any other type of analysis. Understanding the locations and content of these files is crucial to the success of any investigator. Many researchers overlook these records because they do not have adequate knowledge or tools to get the job done. This last part of the section will arm each investigator with the core knowledge and capability to maintain this crucial skill for many years to come.

Exercises

Employ best-of-breed forensic tools to search for relevant e-mail and file attachments in large data sets

Overview

With the increasing use of the Web and the shift toward Web-based applications and cloud computing, browser forensic analysis is a critical skill. During this section, the investigator will comprehensively explore Web browser evidence created during the use of Internet Explorer, Firefox, and Google Chrome. The hands-on skills taught here, such as SQLite and ESE database parsing, allow investigators to extend these methods to nearly any browser they encounter. The analyst will learn how to examine every significant artifact stored by the browser, including cookies, visit and download history, Internet cache files, browser extensions, and form data. We will show you how to find these records and identify the common mistakes investigators make when interpreting browser artifacts. You will also learn how to analyze some of the more obscure browser artifacts such as session restore, tracking cookies, and private browsing remnants.

Throughout the section, investigators will use their skills in real hands-on cases, exploring evidence created by Chrome, Firefox, and Internet Explorer correlated with other Windows Operating System artifacts.

Exercises

Track a suspect'sactivity in browser history and cache files and identify local file access

FOR408.6: WINDOWS FORENSIC CHALLENGE

Author Statement

After 27 years in law enforcement, three capabilities immediately rise to the top of my list when I think of what makes a great digital forensic analyst: superior technical skill, sound investigative methodology, and the ability to overcome obstacles. SANS FOR408: Windows Forensic Analysis was designed to impart these critical skills to the students. Unlike many other training courses that focus on teaching a single tool, FOR408 provides training on many tools. While there are some exceptional tools available, we feel that all forensic analysts need a variety of tools in their arsenal to be able to pick and choose the best tool for each task. However, we also understand that forensic analysts are not great because of the tool(s) they use, but because they artfully apply the right investigative methodology to each analysis. A carpenter can be a master with all his tools and still not know how to build a house. FOR408 teaches students to apply digital forensic methodologies to a variety of case types and situations, allowing them to apply in the real world the right methodology to achieve the best outcome. Finally, the course teaches and demonstrates the problem-solving skills necessary to be a truly successful forensic analyst. Almost immediately after starting your forensic career, you will learn that each forensic analysis presents its own unique challenges. A technique that worked flawlessly for previous examinations may not work for the next one. A good forensic analyst must be able to overcome obstacles through advanced troubleshooting and problem-solving. FOR408 gives students the foundation to solve future problems, overcome obstacles, and become great forensic analysts. No matter if you are new to the forensic community or have been doing forensics for years, FOR408 is a must-have course.

Former students have contacted me regularly about how they were able to use their digital forensic skills in very real situations that were part of the nightly news cycle. The skills you learn in this class are used directly to stop evil. Graduates of Windows Forensics are the front-line troops deployed when you need accurate digital forensic and media exploitation analysis. From analyzing terrorist laptops to investigating insider intellectual property theft and fraud, SANS digital forensic graduates are battling and winning the war on crime and terror. Graduates have directly contributed to solving some of the toughest cases out there because they learn how to conduct analysis and run investigations properly. It brings me great comfort knowing that this course places the correct methodology and knowledge in the hands of responders who thwart the plans of criminals or foreign attacks. Graduates are doing just that on a daily basis. I am proud that the SANS FOR408 course helped prepare them to fight and solve crime.

- Rob Lee

Digital forensics has never been more in demand than it is today. Zettabytes of data are created yearly, and forensic examiners will increasingly be called in to separate the wheat from the chaff. For better or worse, digital artifacts are recorded for almost every action, and the bar has been raised for investigators working to repel computer intrusions, stop intellectual property theft, and put bad actors in jail. We wrote this course as the forensics training we wish would have been available early in our careers. Keeping up with the cutting edge of forensics is daunting, but with frequent updates I am confident this course provides the most up-to-date training available, whether you are just starting out or are looking to add new skills to your forensic arsenal.
